That explains why Roxas looks like Ven, because when Sora's heart was released, Ven's heart was released as well, and Ven's heart became Sora's no body, Roxas. It also explains how Roxas has a heart, despite him being a no body, or so as i understand it.
Thanks for the link. I've been looking for this for quite a while, and I couldn't find it. Thanks again.
